Exchanging server space for small sites and backlinks, does anyone do this here?

[johnnyloadproductions]

I was wondering if anyone here does server space exchanges, if it's a good idea? For building business relationships aside from just other benefits (and risks).

I'd be willing to setup a wordpress multisite if someone wanted to point there domain to my server and possible do a exchange of links of some kind.

Curious, any takers, what do you think?
